Sex and drugs were underlying themes at the New Yorker Festival over the weekend. Speaking to a mostly female audience Saturday night, Jake Gyllenhaal noted that he’d “masturbated four or five times in four or five different movies.” Self-professed former drug user James Taylor revealed he once thought about becoming a chemist, adding with a chuckle, “I guess you could say I dab bled in that.” On Sunday, Kris ten Wiig — at a panel with her “Saturday Night Live” castmates — described her au dition for the show: “Lorne [Michaels] and I made love. For three days.”
